Answer:
131 + 49 = 100 + 30 + 40 + 1 + 9 = 180
Explanation:
First we have to separate the individual numbers 131 and 49 into their hundreds, tens and ones. 131 can be separated into 100, 30 and 1 because there is a 1 in the hundreds place, a 3 in the tens place, and a 1 in the ones place. Therefore, 100 + 30 + 1 = 131.
49 can be separated into 40 and 9 because there is a 4 in the tens place and a 9 in the ones place. Therefore, 40 + 9 = 49.
If we are adding these two numbers together by separating them into their hundreds, tens and ones, we will need to add the numbers together that make up these numbers (100 + 30 + 1 + 40 + 9).
I hope this helps:)
